Claims. (Cl. 33-56) This invention relates to gunsights, and in particular to certain new and useful improvements in a field-shooters gunsight for shotguns.

An object of the invention is to provide a gunsight for shotguns which is adjustable to take care of the trajectory of rifled slugs in a shotgun at distances from 65 to 100 yards or over.

A further object is to provide a sight of the disc type which is adjustable to the right or left to take care of windage requirements.

Yet another object is to provide a shotgun sight mechanism which may be readily applied to or removed from the breech of shotguns of any gauge.

Another object is the provision of a sight of this type which will fit any diameter shotgun barrel or barrels; i. e., under and over, or parallel double-barrel shotguns.

A further object is to provide a sight for shotguns that is cheaply constructed of sheet material, such as sheet metal, and which may be quickly applied to or removed from the breech of a shotgun.

Other objects will appear hereinafter throughout the specification.

In the drawings:

Figure 1 is a side elevation of a shotgun shown in dotted lines with the sight of this invention applied thereto;

Figure 2 is a front elevation of one form of the sight;

Figure 3 is a top plan view of the structure shown in Figure 2;

Figure 4 is a view similar to Figure 3 with the wing nut removed and the bolt shown in section;

Figure 5 is a vertical sectional view taken on the line 55 of Figure 2; and

Figure 6 is a front elevational view of a slightly different form which the invention may take.

The sight shown in the several figures of the drawings is constructed preferably of a single piece of spring material, such as spring sheet metal, to which is attached rubber or plastic sleeves, and to which is also attached the peep sight.

Referring to Figures 1 to 5, the sight shown consists of the spring arms 10 and 12 having bowed or hair-pin portions 14 and 16 and a top depressed portion 18, respectively.

As seen in Figure 4, depressed portion 18 is provided with a slot 20 in which is mounted the bolt 22. The lower end of the bolt supports the peep sight 24 having a central opening 26. As seen in Figure 4, the lower end of the bolt may be square in cross section as shown at 28, so as to prevent rotation of the bolt and the sight within slot 20. The upper end of the bolt is screw threaded at 30 for the reception of the wing nut 32.

The wing nut may be rotated so as to clamp the sight 24 at any adjusted position within the slot 20. This right or left adjustment of the peep sight is for the purpose of adjusting for windage. Should adjustment be necessary, the nut is loosened on the bolt, and the peep sight mounted thereon is adjusted to the desired position whereupon the nut is retightened.

It will be noted that the depressed portion 18 serves to protect the nut from undesired movement, due to the hair-pin portions 14 and 16. These latter project upwardly on each side of the depressed portion and prevent objects such as limbs of trees brushing against the wing nut while the gun with the sight mounted thereon is being transported from place to place.

The lower ends of the spring arms 10 and 12 are provided with sleeves 34 and 36 which are of rubber or plastic material. These sleeves prevent marring of the shotgun breech by the arms 10 and 12 of the sight.

By reference to Figure 5, it will be noted that the peep sight 24 is provided with an extension, or rightangled portion 38, which mounts the bolt 22.

Due to the spring arm construction, the shotgun sight of this invention may be readily attached to shotguns of various gauges. The sight may be applied to gun barrels of various diameters, i. e., gauges, by merely moving the spring arms 10 and 12 outwardly, such as is shown in dotted lines in Figure 2, until the arms extend on either side of the breech. Upon release of the arms, the sleeves 34 and 36 will resiliently hold the sight in position. The sight has a built-in elevation due to the fact that it may be adjusted in a plane which coincides with the longitudinal axis of the shotgun.

Referring to the slightly modified form shown in Figure 6, the spring arms are indicated by numerals 40 and 42, the lower ends of which are encased within sleeves 44 and 46, respectively. As distinguished from the structure shown in Figure 2, the form shown in Figure 6 is provided with semi-circular portions 48 and 50 that correspond to portions 14 and 16 of the first form. Additionally, the Figure 6 form shows a substantially horizontal depressed portion 52, that is provided with a slot, not shown, similar to that shown in Figure 4 of the first form of the invention, and a peep sight 54 having an opening 56, and an extension 58. As in the first form, this extension is similarly shaped and mounts the bolt 60 having mounted thereon by means of screw threads 62, the wing nut 64.

The improved shotgun sight of this invention includes the following advantages: The sight may be used for shotguns using rifled slugs to increase the ballistics and trajectory characteristics beyond 65 yards, and it may be quickly and easily applied to and removed from the breech of various caliber shotguns. The sight is adjustable for windage, and it has a built-in elevation to take care of the trajectory of rifled slugs from 65 to yards and over.

The gunsight of this invention provides a built-in elevation due to the fact that the rear sight is of such distance above the barrel as compared with the front sight, so as to take care of the trajectory of rifled slugs in a shotgun. The gunner, when centering the front bead in the rear peep sight, is forced to raise the muzzle of the gun to align the target with the front bead and the rear peep sight, this automatically taking care of the trajectory of rifled slugs in a shotgun.

The above description and drawings disclose several embodiments of the invention, and specific language has been employed in describing the several figures. It will, nevertheless, be understood that no limitations of the scope of the invention are thereby contemplated, and that various alterations and modifications may be made such as would occur to one skilled in the art to which the invention relates.
